GCSE Maths Practice: pythagoras-theorem

Question 3 of 10

This question requires finding a missing side of a right-angled triangle using Pythagoras' Theorem.

‹ ›

\( \begin{array}{l}\text{In a right-angled triangle, one side is 6 cm and the hypotenuse is 10 cm.}\\ \text{Find the length of the missing side.}\end{array} \)

Choose one option:

Rearrange formula: b = √(c² - a²).

For a right-angled triangle with one side 6 cm and hypotenuse 10 cm, the missing side b can be found using a^2 + b^2 = c^2. Here, 6^2 + b^2 = 10^2 → 36 + b^2 = 100 → b^2 = 64 → b = 8 cm. Practising missing side problems develops problem-solving skills and reinforces the understanding of the theorem's application.
